108217 divided by 77 
The aim is to understand the frequency of 77 in 108217.

Going ahead to step 1:
77 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 77

Step 2:
77 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 77

Step 3:
The number 77 fits into 108 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 108 leaves us with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 77

Let's proceed to step 4:
77 goes into 312 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 308 away from 312, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 77

Step 5:
77 goes into 41 0 times with a remainder of 41.
The next digit of our result is 0. 
Result so far: 140.0
If we subtract 0 from 41, we get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 77

Advancing to step 6:
When dividing 417 by 77, we get 5 with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 1405.0
Deduct 385 from 417 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
When dividing 320 by 77, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1405.4
Deduct 308 from 320 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 77, we get 1 and a remainder of 43.
The next digit of our result is 1. 
Result so far: 1405.41
Subtract 77 from 120 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
When dividing 430 by 77, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1405.415
If we subtract 385 from 430, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
77 goes into 450 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 1405.4155
If we take 385 away from 450, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 1405.4155, and the remainder is 0.00065.
